Printing from a 3D Scan

Recommended Posts

I mentioned this over on the Google Group a few days ago, but now that I've actually got a really nice print out of this, I thought I'd post it here too.

One I made earlier...

 

This was a 4.5hr print at 90mm/s, 0.06mm layers. It turned out really nicely, and is going to need almost no clean up work.

 

It started life as a 3D scan of my daughter, done using Skanect, and a Primesense Carmine v1.09 sensor (with http://www.thingiverse.com/thing:98833). I then cleaned it up using ZBrush, which I'm still just learning (but highly recommend based on my experience with it so far):

 

 

 

The finished 3D model that I printed from can be explored here:

these scans have really nice details!

Is that only due to the lenses or also a different sensor than the Kinect?

When I make scans with the Kinect it loses a lot of detail in the eye, nose, ears and mouth.

Hair and clothes come out fine.

Skanect (mac) is a nice program with quick restoring and reconstruction features.

The Carmine v1.09 has a higher resolution sensor than the Kinect, and is optimised for a closer usage distance - which the glasses then further amplify. I've used an XBox Kinect in the past, but get substantially better results with the Carmine.

 

Hi,

I,m using an Xbox Kinect with a USB adaptor on my windows7 laptop. For scanning I've downloaded the windows toolkit SDK 1.7. You can adjust the scandepth from 8 to 0.35 mtr.

I got myself a Nyko zoomlens and wrecked a pair of reading glasses, but for me that makes no notable difference.

For my setup the limit seems to be the laptop, I've made some pretty detailed scans.

In the sdk toolkit you can adjust the 'cutout' off the object real easy.

But I have not been able to do a 360 scan on the highest resolution yet.

I'll give that zbrush a try, for cleaning the scan, using meshlab now.

Received my Primesense Carmine 1.09 a couple of days ago and have made some half way decent scans via the free version of Skanect. Hope to complete the reading glasses add on today.

Very impressed by your video and, of course the finished model. Am I right in thinking that it is necessary to have the pro version of Skanect to be able to progress to the cleaning stage?

I was staggered by the cost of zBrush - have you tried cleaning a scan with Sculpturis?

Mike.

Sculptris works for the basic shuffling around of material, but doesn't have a way to remesh... so you can't fold stray bits of the model together and rejoin as you can with ZBrush; the topology just gets ever more knotted. You may be able to do it with Blender, I'm not sure. Or perhaps you can use Sculptris with something like Meshlab to re-topologize the whole thing after you're done.

Yes, ZBrush is pricey. But on the other hand, it's comparable to the pricing of pro tools like Photoshop or Illustrator, and significantly cheaper than most pro CAD applications. I think it's probably the most expensive program I've ever spent my own money on (rather than my employer's). But I actually consider it to be extremely good value for money. It is an amazingly powerful and capable program.

Thanks - I'll get to grips with Sculpturis and try with Meshlab and see whether that's good enough.

I can export an .obj file from the free version of Skanect and Scupturis will load it. I can export from Sculpturis as a obj file and import that into Meshlab, and export from Meshlab as an .stl file so there is a possible - free - work flow. Now for a bit of learning and evaluation.

Mike.

EDIT. Realised that the free version of Skanect is crippled by the limitation on the number of faces that can be exported to 4,000 (I think that's what the number was - I've splashed out on the Pro version now).
